Scale

| isPrimitive | true |
| naturalLanguageDefinition | A unit of measure that, when paired with a number, unambiguously describes the magnitude of a physical quantity. |
| primitiveRationale | A comprehensive definition of the notion of scale is beyond the scope of IDO. |
| usageNote | OWL data ranges can capture the acceptable numerical range for a scale. For instance, the 'datum value' of any 'quality datum' that has Celsius as 'datum uom' can be limited to the range from -273.15 upwards to infinity. |
| 'scale' corresponds to the common sense notion of unit of measure which unambiguously defines the magnitude of the measure. | |

| scopeNote | Arguably, IDO conflates the notions of "unit of measure" and "scale" in an unhealthy way. While a unit of measure is a definite magnitude, a scale arises from fixing a number range to express multiples of the unit of measure. One may argue that a unit of measure has an implicit scale, obtained by multiplying the unit by any number; this will then allow for undefined or meaningless expressions like "minus 10 Kelvin". |
